This is a great looking template and I added a twit this button to this one fairly easy and you can also, first go into layout of your template and click the Edit HTML, then expand widgets and look for this code;

After this code is your bookmark codes, go download you a 24 x 24px twitter button and pick a place to add it, either at the end or make room before the end to add it, upload your twitter button to blogger and check the edit html code in your editor and look for the src=the http link, by coping this link you can make the image appear without hosting it anywhere just save now the twitter button after giving the post a name and then copy the src=(url) to use to display the twitter image in your book mark section like this;

This will add a twitter this image to all your posts as well as the other links that are provided in this template, and if not twitter add other social bookmarks this is a neat template give it a try, and remember the twitter image you saved in the post you made you have to go into edit HTML of your editor to find the src='IMAGE LINK'.Download Note Guy
